As Eric underlines, -catplot- is a user-written command from SSC. As always, please remember to explain where user-written commands you refer to come from. Developing Eric's comments just very slightly: -catplot- is just a wrapper (in this case) for -graph bar-. Broadly speaking, -graph bar- knows nothing about categories that might exist but are not matched by observations. If you are prepared to do a bit of work you can use -twoway bar- to show a bar chart with whatever axis labels you want, which need not correspond to existent categories. sysuse auto, clear contract foreign su _freq, meanonly gen percent = 100 * _freq/r(sum) gen text = string(percent, "%2.1f") twoway bar percent foreign, base(0) barw(0.6) /// || scatter percent foreign, mlabel(text) ms(none) mlabpos(12) /// yla(0(25)75, ang(h)) xla(0 1 2 "Other", val) legend(off) There is an essay in this spirit at SJ-8-2 gr0034 . . . . . . . . . .

Cox Q2/08 SJ 8(2):269--289 outlines techniques for producing table-like graphs Nick n.j.cox@durham.ac.uk Eric Booth The value "2" and its label "other" are never "chosen categories" as far as -catplot-, and Stata for that matter, are concerned. It's important to realize that adding a label for the value "2" where there is never actually a value of "2" for the variable (foreign) does not change the summary statistics for that variable. There's likely a better solution than this, but you could add a new observation with the value "2" for foreign to a very large dataset where that new observation will account for <.1% of the data, so it looks like "other" has a 0% label. You could temporarily -expand- the dataset and the relative percentages each category would remain the same as the unexpanded data (but be aware of what you are doing here and what it is doing to your data): ***********! sysuse auto, clear label define origin 2 "other", add label li origin ta for, miss catplot foreign, recast(bar) percent blabel(bar, position(outside) format(%5.1f) /// size(medium) color(red) ) ytitle(Prozent) ylabel(0(10)100, labsize(small)) preserve expand 1000 set obs `=_N+1' replace for = 2 in `=_N' ta for, miss catplot foreign, recast(bar) percent blabel(bar, position(outside) format(%5.1f) /// size(medium) color(red) ) ytitle(Prozent) ylabel(0(10)100, labsize(small)) restore ***********! Also, it's worth mentioning that -catplot- is a user-written package by NJC available from SSC.
